1. 32-bit technology. 2. Optically isolated differential input signals. 3. Ultra-low noise and vibration. 4. 2-256 microstep setting range. 5. Can drive 4/6/8 line two-phase 6. Current value can be randomly set within rated value. 7. The current is automatically halved at rest. 8. Impulse response frequency up to 250kHz. 9. With overvoltage, undervoltage, short circuit protection. 10. Alarm output function I/O . Introduction: The 2DM860H is a new digital driver. It uses the latest 32-bit DSP control technology. The can set the subdivision to 25600 and the current value to the rated current. The driver uses built-in -segmentation technology. Smoothness and noise are greatly improved in low subdivisions. The internal integration of is an automatic adjustment function that automatically adjusts the optimal operating parameters of the different motors to maximize the performance of the motor.
